Despite the hundreds of Mobile-Assisted Language Learning (MALL) publications over the past twenty years, statistically reliable measures of learning outcomes are few and far between. In part, this is due to the fact that well over half of all MALL-related studies report no objectively quantifiable learning outcomes, either because they did not involve MALL implementation projects, or if they did, learning gains were only based on subjective teacher assessments and/or student self-evaluations. Even more so, the paucity of statistically reliable learning outcome data stems from the short duration of projects and small numbers of students involved. Of the 291 distinct studies examined in this review only 35 meet minimal conditions of duration and sample size, i.e., ten experimental subjects over a period of at least a month. Sixteen of these suffer from serious design shortcomings, leaving only nineteen MALL studies that can reliably serve as a basis for determining the learning outcomes of mobile-based language applications. Of these studies, fifteen can be considered to report unequivocal positive results, with those focusing on reading, listening and speaking without exception evidencing a MALL application advantage. Four studies, all focusing on vocabulary, reported no significant differences.

In this paper the development of mobile-assisted language learning (MALL) over the past 20 years is reviewed with a particular focus on the pedagogical challenges facing its exploitation. Following a consideration of the definition of mobile learning, the paper describes the dominant mobile technologies upon which MALL applications have been based: MP3 players, personal digital assistants, and mobile phones. It then identifies the prevalent methodological approach that has underlain the great majority of MALL implementations: a behaviorist, teacher-centered, transmission model of instruction. However, though rarely implemented, MALL is equally capable of supporting more innovative constructivist, collaborative, learner-centered instruction, examples of which are examined. Besides being restricted by a pedagogical approach very much out of step with methodologies that have guided foreign language teaching for nearly four decades, MALL has also been constrained by access to technology. In part, this problem has been due to the necessity of acquiring mobile devices for student usage and the costs associated with mobile network and Internet connections. Even more so, the exploitation of mobile devices for language learning has been hampered by a lack of hardware standardization and entrenched operating system incompatibilities. The paper concludes that MALL has yet to realize its full potential and that achieving this aim is more a matter of pedagogy than technology. The financial and technological factors that have impeded the effective exploitation of MALL are likely to be resolved as operating system incompatibilities are overcome by market forces and students as well as teachers acquire suitable mobile devices for their own personal use. The future of MALL lies in the exploitation of the communication and multimedia affordances of mobile devices in ways that support collaborative, task-based learning both within and outside of the classroom.

The aim of this study is to comprehensively evaluate quantitative experimental mobile-assisted language learning (MALL) studies published between 1994 and 2019 that meet minimal conditions of research design and statistical analysis. Starting with a bibliographical database of 1,144 references to experimental MALL implementations, of which there were 700 objectively substantiated by quantitative experimental language learning outcomes, only 84 experimental MALL studies met the inclusion requirements. Their analysis addresses two critical sets of research questions. First, what are the general characteristics of the selected studies and, second, what are their language learning outcomes in terms of measured effect size. Nine general characteristics are considered: publication source, chronological distribution, country of origin, institutional environment, sample size, intervention duration, targeted language, language learner competence level, and learning focus. Effect size was calculated separately for between-group (independent, experimental) and within-group (quasi-experimental) treatment studies. In both cases, the overall results were quite large: 0.72 for the former and 1.16 for the latter. An analysis of four critical moderator variables (language learner competence level, language area focus, institutional environment, and intervention duration) revealed similarly large effect sizes. Notwithstanding, analysis of the data also confirmed obvious publication bias and a very high level of heterogeneity that frequently approached 100%. The relevance of positive language learning outcome conclusions thus needs to be tempered by these shortcomings.

This study investigated the effectiveness of integrating Student Team Achievement Division (STAD), a structured cooperative learning method, and WebQuest, an inquiry-based technological model (IBTM) on developing university English as a Foreign Language (EFL) students’ advanced-level argumentative writing skills and enhancing instructors’ positive perceptions about teaching and learning. The study, which was undertaken over a 12-week academic semester, employed a mixed methods pre-test/post-test control/experimental group design whereby six intact rhetoric classes were randomly assigned to experimental and control conditions. The experimental group participants (N = 54) were enrolled in four classes and received argumentative writing instruction incorporating STADIBTM whereas their control group counterparts (N = 24) were enrolled in two classes and received the same argumentative writing instruction without STADIBTM. Four instructors who were involved with the experimental group received training on the implementation of STADIBTM. Qualitative data collection and analysis were utilized. The argumentative essay pre-tests and post-tests along with pre-treatment and post-treatment surveys were used to collect data. The quantitative results were evaluated using ANCOVA analyses. The findings showed that only the less skilled participants of the experimental and control groups were able to significantly improve their argumentative writing. However, their instructors were able to develop more positive pedagogical perceptions and perceived fewer challenges because of STADIBTM-based instruction. Further recommendations are given.

This paper describes trends in instructional technology that are influencing foreign language teaching today and that can be expected to increasingly do so in the future. Though already an integral part of foreign language instruction, digital technology is bound to play an increasing role in language teaching in the coming years. The greatest stimulus for this will undoubtedly be the accessibility of Mobile-Assisted Language Learning (MALL), made possible through the exploitation of mobile devices owned by students themselves. The ubiquitous ownership of smartphones and tablet computers among adolescents and adults now makes a Bring Your Own Device (BYOD) approach a feasible alternative to desktop computer labs. Making this work, however, especially in a financially and technologically restricted environment, presents a number of challenges which are the focus of this paper.
